I bring here a drama with css height.
I would like to make a layout, a div that contains 2 divs both in same line, one is resizable and the other must fit in the parent's height (same height as the first one).
The first div can have additional information (so i can't fix the height), so it will have more lines, the important is that it must not have a scroll bar. The second div must obey the first height, if it's bigger than it will have a scroll bar.
<div class='container'> <!-- parent -->
<div class='left'> <!-- resizable -->
</div>
<div class='right'> <!-- same height as left div -->
</div>
</div>
UNSOLVED CODE
The problem is that i can't figure out how to make it just using css. Or even it's possible just with css. I would not like to use js.
Someone please help me!
Fiddle
What you do is make the right one absolutely positioned which stops its height influencing the parent's.
RELEVANT CSS
.container {
background-color: gray;
display: table;
width: 70%;
position:relative;
}
.container .left{
background-color: tomato;
width: 35%;
}
.container .right{
position:absolute;
top:0px;
left:35%;
background-color: orange;
width: 65%;
height:100%;
overflow-y: auto;
}

I have been banging my head against the wall trying to figure out this problem and I have looked high and low for the answer and came up with similar results.
Synopsis
The problem is that I am building a website using the 960 grid and have three columns that I want to stretch at 100% at all times. Here is a fiddle for your reference: http://jsfiddle.net/Uec7h/1/
Essentially the html is like so:
<div class="contentWrapper">
<div class="container_12">
<div class="grid_2 leftSide clearfix">
Left sidebar content.
</div>
<div class="grid_7 content">
Lots of content loaded from the server.
</div>
<div class="grid_3 rightSide">
Right sidebar content.
</div>
</div>
</div>
with the CSS being like
html, body {
height: 100%;
}
.content {
height: 100%;
}
.leftSide {
height: 100%;
background-color: #000000;
}
.rightSide {
height: 100%;
background-color: #000000;
}
.contentWrapper {
height: 100%;
}
The fiddle isn't completely accurate to what I am seeing on my local version, but it's close. Seems like the left and right sidebars do not want to expand to 100% no matter what I do.
What I've Tried
Most of the answers I have found on SO have suggested to put height: 100% on the html, body elements and everything should work out fine. Adding this attribute and giving both sidebars height: 100% did work a little bit, but if the content in the middle column gets too big, it stops at a certain point and won't continue to stretch.
I have tried adding the clearfix class that comes with the 960 grid but it didn't seem to help at all.
Question
How do I get the left and right side bars height in the fiddle to be 100% no matter what content is in the middle column?
If you add the following CSS to the sidebar elements it will fill the 100% of the height.
display:block;
height:auto;
position:absolute;
top:0px;
bottom:0px;
If you place the sidebar into a wrapper div with relative positioning, the content section will be again in it's right place...
I would also set padding and margin to 0 for the body.
EDIT:
If you add height: 100% to the .container_12 it will get a real height, and children elements can have a 100% height. Notice that the sidebars will be as height as the window itself, but your content at the middle can be taller than 100%... Fiddle
Dont know the 960 grid, the EDITED solution - using visibility: visible; -
HTML
<div id="box">
<div class="vision"> sdfsdfsd </div>
</div>
CSS
#box {
float: left;
border: 2px solid red;
}
.vision {
width: 300px;
height: 600px;
visibility: visible;
}
I was under the impression that when using % or auto for margins on a div contained within another div the position would be calculated in respect to the parent div.
So if I have a div with height: 50%, margin-top: 25% and margin-bottom: 25% the box should centre vertically within the parent div.
When I do this though the div centres on the page not the parent div.
The CSS
div#header {
width: 100%;
height: 100px;
margin: 0px;
position: fixed;
}
div#leftnavigation {
height: 50%;
margin-top: 25%;
margin-bottom: 25%;
float: left;
}
And the HTML
<!--Title and navigation bar-->
<div id='header'>
<!--Left navigation container-->
<div id='leftnavigation'>
<p>efwfwgwegwegweg</p>
</div>
</div>
In my case there are other divs floated to the right of the one detailed above, but any one of them behaves the same way. I'm assuming I'm doing something daft but I've been over all the other questions I could find along these lines and still can't figure it out.
EDIT
Here's the JSFiddle as requested http://jsfiddle.net/ChtVv/
UPDATE
I've tried removing the margin constraints and setting the leftnavigation div to height: 100%, this works so the issue is with the margin attribute?
The reason it didn't work is that percentage-margins are percentages of the parent's width, not its height. You can tell this by using margin-top: 25px; margin-bottom: 25px;, and also by increasing the width of the right-panel in jsFiddle.
In all cases % (percentage) is a valid value, but needs to be used
with care; such values are calculated as a proportion of the parent
element’s width, and careless provision of values might have
unintended consequences.

CSS is tricky!! :D
This is a borrowed technique to centre vertically and horizontally, but it would involve changing your HTML and CSS. I am not sure how flexible you are with your code:
CSS:
#outer {width: 100%; border: 3px solid red;}
#middle {width: 100%; text-align: center;border: 3px solid green;}
#inner {width: 200px; margin-left: auto; margin-right: auto; text-align: left;border: 3px solid blue;}
/* Courtesy: http://www.jakpsatweb.cz/css/css-vertical-center-solution.html */
HTML
<!--Title and navigation bar-->
<div id='outer'>
<!--Left navigation container-->
<div id='middle'>
<p id="inner">efwfwgwegwegweg</p>
</div>
</div>
You can build upon this to achieve whatever you are after!

Ok, so there are a lot of reasons why this would not work.
The main reason would be that your container has position:fixed;
When adding position:fixed; to a element, it no longer reserved it's space in the DOM and won't contain it's children.
I have made a example of the best way (in my Opinion) to center your child both Vertically & Horizontally
Here is a demo.
Demo
And here is the code.
<div id="container">
<div id="child"></div>
</div>
#container{
width:100%;
height:500px;
background:#CCC;
margin:0;
}
#child{
width:50%;
height:50%;
background:#EEE;
position:relative;
top:25%;
left:25%;
}
I have something like this:
<div class="top">top</div>
<div class="container">
<div class="left">left</div>
<div class="right">right</div>
</div>
<div class="bottom">bottom</div>
Relevant code in jsFiddle
As you can see, between top and bottom divs, there is a div container. I want this div container to move bottom dive as much as is needed (and i don't want it to be a fixed value - that means if, lets say left container will get much higher - the bottom div will be pushed down as well.
How can i do that?
This is a simple seeming problem that ends up being kind of tricky. The above suggestion about position:relative vs. position:absolute are a good first step. After that you need to make some room for the set width right div:
.left {
height: 100%;
min-height: 50px;
border:1px dashed red;
padding-right: 50px; <---
}
Then float your right div in the space you made:
.right {
float:right; <---
width: 50px; (This needs to match the padding-right value above.)
text-align: right;
min-height: 50px;
height: 100%;
border:1px dashed blue;
}
Finally, put the right div before the left div in the html:
<div class="top">top</div>
<div class="container">
<div class="right">right</div>
<div class="left">left</div>
</div>
<div class="bottom">bottom</div>
(Tested in Chrome and IE.)
See: Right div fix width, left div extend to max width?
You can check out a fiddle here: http://jsfiddle.net/x3QfG/1/
Will that work for you?
Right now you're using absolute positions for the left/right div's, so you will always need to know the height in order to position the bottom div correctly. What you want to do is float these instead, then clear the floats in the bottom div. That way the left/right can be as high as their contents, and the bottom div will always appear below.
.bottom {
clear: both;
}
.left {
float: left;
width: 50%;
min-height: 50px;
}
.right {
float: right;
width: 50%;
min-height: 150px;
}
I've modified your jsFiddle accordingly, and made the right div higher to show how the bottom always appears below.
Use floats rather than positioning them absolutely. That will make your architecture very much fluid and flexible.
After you apply necessary float values to your .left and .right, use a clearfix hack to contain your floated elements within the container. Now whenever any of the .left or .right divs increase in height, the bottom div will be pushed down.
Make Container Relative and left and right absolute,and for positioning set width rather than using float.
I need to do a website with divs. See the code snippet for the format. The MENU is of variable height, depending if the menu-items is rolled out or not, and the content is of variable height as well, but with a minimum of 700px. If the MENU is folded together to its min-height, it is 300px, and the BOX should take up the remaining space so MENU+BOX is the same height as the CONTENT. The content of BOX is 600px, so when BOX only gets 400px, there should be scrollbars. When the CONTENT div expands, the BOX should expand as well, so they stay the same height.
Here's what i got so far, but it is not working properly. I've tried some other stuff, but deleted it for this post so I only get the points shown instead. Hope you can help, and thank you in advance!
#container{ width: 800px; }
#leftbar{ float: left; width: 250px; background-color: lightgray; }
#content { float: left; width: 550px; background-color: white; }
#menu { width: 250px; }
#box { width: 250px; height: 300px; overflow-y: scroll; }
<div id="container">
<div id="leftbar">
<div id="menu">
<div id="box">
</div>
<div id="content"></div>
</div>
<div style="clear:both;"></div>
hi at the first look i can see you have some unclosed div tags, and probably that's why it doesn't do what you want. You can assign scroll bars by using java script, if you set overflow from the css it will have a scroll bar from the beginning
I want to make a web page that uses 100% of screen space. I have two divs:
1st - menu with fixed width (~250px)
2nd - whats left
The misleading part for me is that the menu div is not in the 2nd div. They both are in a wrapper div (100% width). The problem is that if I write 100% width for the 2nd div, it goes below the menu. If I write less %, I cannot be sure how it will be displayed in smaller resolutions.
Is there is some negative sizing or something? ATM. 1st div floats left and 2nd div float right.
UDPATE: here is some code:
div.main {
width: 100%;
}
div.1st {
width: 250px;
float: left;
}
div.2nd {
width: 100%; #here should be the space that is left in the main div#
float: right;
}
<div class="main">
<div class="1st">menu</div>
<div class="2nd">content</div>
</div>
Problem: content could be as wide as it needs to so if string or objects in it is big enough 2nd div goes below 1st. Menu width is fixed.
UPDATE #2: if i leave content width empty then it will also goes below menu since content is wide enough
Take a look at this Post, there you have the correct solution:
http://www.alistapart.com/articles/holygrail
You could do something like this : http://jsfiddle.net/steweb/78x8y/
markup:
<div id="container">
<div id="left">Width=> 250px, float left</div>
<!-- following div takes automatically the remaining width, no need to declare further css rules -->
<div id="remaining">Width => the remaining space</div>
</div>
css:
#container{
width: 100%;
float:left;
overflow:hidden; /* instead of clearfix div */
}
#left{
float:left;
width:250px;
background:red;
}
#remaining{
overflow: hidden;
background:#DEDEDE;
}
Yes, you can determine the width of absolutely positioned elements by setting left and right. This makes the browser solve the equation in the standard for width. See this demo for an example.
